LOCK BLOCK FOR STEEL BEDSPRINGS.

Application filed July 11,

T 0 all whom it may concern Be it knownthat I, ARcH E J. Mnrz, a citizenof the United States of America, and a resident of Cincinnati, in thecounty of Hamilton and State of Ohio, have invented a new and usefulImprovement in a Look Block for Steel Bedsprings, of which the followingis a specification.

My invention relates to metal bed construction, and to the means forsupporting the spring mattress frames carried thereby, more particularlyrelating to the casting member employed for connecting the side railswith head and foot iron cross-bars to which the so called spring bedbottoming or mattress supporting wire structure is connected.

An object of my invention is to provide mounting means of the typereferred to wherein the members are positively precluded fromseparating.

Another object of my invention is to provide a simple and eflicientconstruction of the parts.

These and other objects are attained by the means described herein anddisclosed in the accompanying drawings, in which- Fig. 1 is an elevationof a coupling member, or bracket, made in accordance with my invention,illustrating one of the angle iron crossbars in proper position withrelation thereto.

Fig. 2 is an end elevation of the parts shown in Fig. 1.

Fig. 3 is a fragmental view showing the manner of mounting the angleiron on the bracket.

The bracket A is attached to the side bar B of the bed frame in anysuitable manner such as providing the bracket with a socket or bore (itwithin which the end of the side ba B extends. The end of the bracket A,spaced from the side bar B, has a block a formed upon it. The block hasa slot a extending therethrough transversely to, or at right angles to,the side bar B when mounted on the bracket. The inner portion a of theblock. or in other words that portion of the block formed immediatelyadjacent the central part or arm a of the bracket, extends upwardlybeyond the slot a and has its outer face (i disposed at substantiallyright angles to the axis of the bore a in the bracket and extendingabove the slot a The outer portion a of the block extends from the innerportion of the block Specification of Letters Patent.

like a flange, terminating about midway of the height of'the block andhas its inner face a extending in substantial parallelism with the facea formed on the block. The face a formed on the inner portion a of theblock, lying in the slot 64 and disposed opposite to the fare a extendsdownwardly and toward the socket formed in the bracket. A stud Or pin (4extends from the face a of the block portion a and extends over the slota An angle iron D has formed on its one side plate (Z, a hole d ofsuflicient size to accommodate the stud a. The side plate (Z of theangle iron is made of a thickness substantially equalv to theperpendicular dis tance between the parallel faces a and 0 formed on theblock. The face a formed on the block interiorly to the slot, isinclined at such an angle that the free end or lower end (Z of the sideplate (Z may be projected into the slot without interference from thestud a. After the lower end of the side plate has been inserted in theslot, the side plate is moved toward the innermost portion a of theblock so that the opposite sides of the side plate engage the faces aand a, whereupon the stud a is projected into the slot d formed in theangle plate. The other side plate d of the angle iron has attached to itthe springs G, such as are commonly employed in the construction of bedsprings. The springs C retain the angle plate in firm engagement uponthe faces a and a of the block and the studs a prevent any lateraldisplacement or movement of the angle iron. The avoidance of lateralmovement of the angle iron is of prime importance, because during theshipment of bed springs, unless the angle iron is retained as shown inthis application, or else riveted to the bracket A, the rough handlingand jolting accorded the springs cause the angle iron to separate fromthe bracket, thereby disassociating the entire bed spring. After theangle iron is mounted upon a block and the springs C are stretchedbetween the angle irons mounted at opposite ends of the side bars B, therough handling and jolting of the springs will not cause the parts toseparate.

hat I claim is:

In a corner member for bed springs or mattress supporting frames and thelike,-

the combination of a bracket attachable to transversely to the side railwhereby a slot is provided between the flange and the balance of theblock, the wall of the slot opposite the flange extending downwardlyaway from the flange and the wall of the bloclc above said slotextending in substantial parallelism with the Wall of the slot formed onthe flange, studs extending from -.the block above the slot, and across-bar, to which the mattress supportingstructure is attached, havinga slotted side plate of 21- thickness substantially equal to the perpen-'dicular distance between the parallel faces ARCHIEJ.
